Vapor Barriers

 Ground moisture constantly evaporates upward through bare soil, creating high humidity that leads to musty smells, mildew, and mold. A properly installed vapor barrier seals the ground, dramatically reducing moisture vapor transmission and stopping these odor and mold problems at the source.

 Excess crawl space moisture can cause wood rot, rust on metal components, insulation damage, and even contribute to higher humidity upstairs, worsening indoor air quality. A vapor barrier helps keep the area drier, preserving structural integrity and reducing the risk of health issues from mold spores circulating through your HVAC system.

 By blocking soil moisture, a vapor barrier helps maintain more stable temperatures in the crawl space, reducing the workload on your heating and cooling system. Many homeowners notice lower energy bills and a more comfortable home year-round after installation.
